he aim of this study was to determine the effect of
incorporation of defatted walnut on the quality of buiscuit
and increase theutilizationofwalnut.Walnutwasdefattedusing
hydrolic pressmethodof oil extraction. Buiscuitswere produced
from the composite flour blends of wheat (Triticum spp) /
walnut (Juglans regia) in the ratio of 100: 0, 90:10, 80: 20, 70:
30, 60: 40 and 50: 50 respectively. Consumer acceptability of the
buscuits were determined using multiple comparismdifference
test by 10 judges. The sensory test was carried out under the
following parameters flavour, texture, taste and colours. The
sensory result reveal that composite buiscuit with 90% wheat
flour and 10%walnut flour had the highest general acceptability
by the panelists which implies there was no significant in
the buiscuit made from from 90% wheat and 10% walnut
flour and therefore was rated best amongst all the samples

flatoxin contamination of dairy feeds and milk was
investigated in 8 Kenyan regions; Kwale, Kilifi, Nyandarua,
Nyeri, Samburu Uasin Gishu and Nandi. The study was initiated
toassess theknowledgeandpractices of dairy value chainactors
as well as the prevalence and levels of aflatoxins (B1, B2 G1,
G2 &M1) in dairy feeds and milk respectively. For this purpose,
180 milk samples were collected dairy farmers, milk traders
and processors. Additionally, 250 feed samples were collected
from dairy farmers, feed traders and feed millers. Feed and
milk analysis for aflatoxin contamination were conducted using
enzyme-linked immunosorbent assay (ELISA). Results showed
presence of aflatoxin M1 in 123(67.8%) of the milk samples.
Aflatoxin M1 contamination exceeded the recommended FAO/
WHO0.05μ/L in all milk samples, ranging from1.1 to 107.3μg/L.
100 feed samples (40%) which were all dairy concentrates
were positive for total aflatoxins of which 69 samples
recorded above the 10ppb Kenya Bureau of Standards (KEBS)
regulatory levels. All the forage grasses (n=80) tested negative
for total aflatoxins while 30 % (n=70) of the crop residues
tested positive for total aflatoxins. Linear regression revealed
a significant association between feed handling practices
and total aflatoxin and AFM1 levels. The results show high
incidences of animal feed contamination along the dairy value
chain which impacts negatively on human health. Regulatory
measures need to be put in place to improve adherence to feed
and milk safety practices across the value chain particularly in
raw materials sourcing, manufacture and distribution of dairy
meal. Government initiatives, effective surveillance systems,
collaboration between the many stakeholders, research
(particularly related to preventative measures), adequate
storage facilities and capacity development and training of the
stakeholders additionally, availability of information on feed
and milk safety standards to dairy stakeholders needs to be
enhanced to ensure safe feeds and milk.
